Description

  The present invention relates to a wire harness manufacturing apparatus.

  Assembly of the wire harness is generally performed by driving a nail-like pin into a flat plate such as a veneer plate to form a pseudo wiring route, and wiring the electric wire along the pseudo wiring route. .

  However, once the pin is driven into the flat plate, there is a problem that it is difficult to change the pin position. In addition, if the equipment incorporating the wire harness changes, the shape and size of the wire harness itself is different, so the plane plate is replaced, and a large storage space is required to store the plane plate until the next manufacturing. There is.

  In view of the above circumstances, conventionally, a wire harness manufacturing apparatus that combines a plurality of rod-like components into a shape corresponding to the shape of the wire harness has been proposed (see, for example, Patent Document 1).

  The wire harness manufacturing apparatus described in Patent Document 1 includes a plurality of hollow square bar-like parts formed by bending a metal plate, a plurality of pins and wire holding parts, and the hollow square bar-like part has an upper surface. A plurality of small holes arranged side by side in the longitudinal direction, a plurality of first connection parts by slits formed on both side surfaces over substantially the entire length, and a second connection part and a third by protrusions respectively formed on both end faces. And a pin and a wire holding part are erected so as to be selectively inserted into and removed from a small hole of the hollow rectangular bar-shaped part, and the plurality of hollow rectangular bar-shaped parts include a first connecting part and a second connecting part. Alternatively, the third connecting portions are connected to each other in a separable manner, thereby being coupled to a shape corresponding to the shape of the wire harness to be assembled.

JP-A-8-83523

  However, according to the conventional wire harness manufacturing apparatus, in order to produce a hollow rectangular bar-shaped part, a large number of small holes and slits must be formed in the metal plate by punching, so the hollow rectangular bar-shaped part is long. As a result, the number of times of punching increases and the time of the punching process increases. Further, when the wire harness has a long overall length, such as a wire harness for a railway vehicle, for example, a large number of hollow square bar-shaped parts must be coupled in the longitudinal direction, and the jig assembly work is burdensome for the operator. .

  Therefore, an object of the present invention is to provide a wire harness manufacturing apparatus that can easily manufacture a jig and can reduce the burden of jig assembling work.
